Ke$ha's 2011 Rock In Rio Festival Performance

She’s always been known for her outrageous party attitude, and Ke$ha brought her A-game to the Rock in Rio music festival earlier today (September 29).

The “Your Love Is My Drug” songstress took the stage with her band for a high-energy performance of her myriad hit songs including "Your Love Is My Drug," "Blah Blah Blah," "We R Who We R," "Cannibal," "Blow" and "Take It Off".

Ke$ha has been a busy girl with her current Get $leazy tour, and she joined an eclectic group of musicians scheduled for the Cidade Do Rock stage.

She played just before Stevie Wonder’s set with other acts in the day's lineup including Jamiroquai, Janelle Monae, and Legiao Urbana.
